BALING-PRESS.

Specification of Letters Patent.

Patented Aug. 5, 1913.

Application filed November 11, 1908. Serial No. 462,074.

To all whom it may concern:

Be it known that I, PLIN C. SoUTHwIoK, a citizen of the United States,and resident of Sandwich, county of Dekalb, and State of Illinois, haveinvented certain new and useful Improvements in Baling-Presses, of whichthe following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof- The invention relatesmore particularly to that class of baling presses in which the materialis compressed against a removable bulkhead, its principal object beingto provide improved means for inserting and securing the bale ties; afurther object being, however, to generally improve the details ofconstruction of the delivery end of the press.

The invention consists in the structure hereinafter described, and whichis illustrated in the accompanying drawings, in which Figure 1 is adetail plan view of the delivery end of the press, partly in section;Fig. 2 is a detail perspective of the delivery end of the press; Fig. 3is a detail, partly in section, of the yoke for locking the bulkhead inplace; Fig. 4 is a detail vertical section of the press; Fig. 5 is adetail of the top of the press showing the manner of securing the tie;Fig. 6 is a detail showing the bottom of the press and plunger and ofthe tie-inserting mechanism; and Fig. 7 is a sectional detail showingthe mechanism for inserting the bale ties.

The press comprises a chambered body 10, usually mounted upon wheels,one of which is shown at 11. Within the chamber of the body 10 a plunger12 reciprocates for compressing the material within the bale cham ber13.

The bulk-head 14 forming the end of the chamber 13 is hinged, as shownat 15, across the end of the top wall 16 of this chamber and swingsupwardly to permit the completed bale to be ejected. The bulk-head issecured, when closed, by an A-shaped lever 16*, pivoted, as shown at 17to a bracket 18 secured to the bottom of the press. The lever 16 bearsagainst a pressure block 19 secured to the bulk-head adjacent its loweredge. This lever is secured, when raised, by means of a yoke 20, pivotedat 21 to the top of the body 10 and swinging upwardly. This yoke carriesa bearing plate 22, which is slidable upon its side members,

24, being ina pair of coiled springs 23,

and a crossterposed between this plate head 25. at the outer end orcrown of the yoke. A rod 26, secured to the plate 22, plays through thehead 25 and has at its outerend a nut 27 for limiting its inwardmovement.

The bulk-head being closed and the lever 16 raised, the yoke 20 isdropped over, its upper end thereby securely locking the bulkhead. Thesprings 23, 24:, are so tensioned that they will yield under pressure ofthe plunger 12 when the bale is sufliciently compressed, thereby servingas means for indicating the completion of the bale and con sequently aclose approximation of the weight of the latter. In practice it isdesirable to form bales of substantially uniform weight, say 200 pounds,and springs may be used and the leverage so proportioned that thebulkhead will begin to yield when the desired weight of materialv hasbeen compressed within the baling chamber.

Heretofore the usual practice has been to insert the bale wires or tiesby hand, and the operation has been laborious and slow. One feature ofthe present invention comprises a set of needles with mechanism foractuating them, whereby the wire is carried up between the compressedbale and the face of the plunger.

The usual longitudinal slots 28 are pro vided in the top of the balechamber and vertical slots 29 in the bulkhead for the in sertion ofwires. One'end of the wire having been inserted downwardly through oneof the slots 28 and outwardly through one of the slots 29, is now thrustinwardly through the lower end of the slot 29 following the longitudinalchannel 30 in the bottom 31 of the bale chamber, to and a little beyondthe inner wall of the co1npressed material. A set of needles carried bya cross-head 33 below the press, enter through suitable apertures 34 atthe inner ends of the channels 30. These needles preferably take theform of flat bars, their widest dimension being transverse to the pressand their upper ends being notched or forked, as shown at 35.

Vertical channels are formed in the front face of the plunger 12 throughwhich the needles may travel in carrying the wire or bale-tie upwardlyalong the rearward face of the bale, these channels being arranged, ofcourse, to register with the apertures 3 when the plunger is in itsforward position. Preferably these channels or ways are secured byforming them in suitable castings 36, which are secured to the frontface of the plunger and project forwardly therefrom as ribs. The topsand bottoms of these castings project forwardly, as shown at 37, suchextensions serving the purpose of rounding the corners of the bale. Thiscasting is also provided with a longitudinal slot 38 extendingthroughout its length, including the top and bottom extensions, andopening to the needle-way or channel, these slots being in register withthe slots 28 and 30 in the top and bottom of the baling chamber.

The sides of the aperture 34 converge at their inner ends for thepurpose of centering the wire as it is inserted through the slot 30.

The cross-head 33 is carried by a pair of rack-bars 39, 40, housed andsliding ver tically in suitable brackets 41 attached to the sides of thepress body. These rackbars mesh with gears 42, 43, mounted upon a shaft44, suitably ournaled in the bottom of the press body, one or both endsof the shaft being squared for the application thereto of a suitablehand crank 45. A stop lug 46 is formed on the upper end of each of therack-bars for the purpose of engaging the bracket 41 tolimit thedownward movement of the needles.

hen the material has been sufliciently compressed to form a bale, asindicated by the yielding of the springs 23, 24, the plunger is stoppedin its advanced position, holding the material under compression. Thewires having been inserted downwardly and outwardly in the slots 28 and29, their lower ends are thrust into the channels 80 through the slots29 until their inner ends strike the contracted ends of the apertures34. The needles are now raised and each of them catching one of thewires carries it upward, its end being folded down along the rearwardface of the needle as the latter enters the channel in the casting 36.As the needle emerges through the top of the press, as shown in Fig. 7,the two ends of the wire are manually engaged, thus completing the tyingoperation, the hook 47 being inserted in the loop 48 in the usualmanner.

The slots 28, 29, and the channels 80 are most conveniently formed byspacing apart the boards of which the press body and the bulk-head areformed. In order to provide a bottom for the channels 30, plates 49 maybe attached to the lower faces of the bottom boards.

Secured to the inner face of the bulkhead 14 and adjacent its lower endis a series of blocks 50, each having a pair of jaws 51, 52, whichreceive the outer ends of the bottom boards of the press body as thebulk-head is closed, thereby preventing spreading of the lbale-chambervertically under the baling pressure. The special function of the upperjaw 51 is to give the bale the rounded corner, as in the case of theelements 87.

I claim as my invention,-

4. In a baling press, in combination, a chambered body, a plungerreciprocable within the body and having channeled ribs across its face,and tie-inserting needles adapted to reciprocate in the rib channels.

5. In a baling press, in combination, a chambered body, a plungerreciprocable within the body and having channeled ribs across its face,such ribs having forward extensions at their ends, and tie-insertingneedles adapted to reciprocate in the rib channels.
